MATRIX-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 475,805, dated May 31,1892.

Application filed July 18, 1890. Serial No. 359.208. (N0 model.)

To aZZ whom it may concern.-

Be it known that 1, CHARLES SEARS, a citizen of the United States,residing in South Evanston, in the county of Cook and State of Illinois,have invented a new and useful Improvement in Matrix-Making Machines, ofwhich the following is a specification.

My object in this invent-ion is the prod uc tion of an improved machinefor making matrices from which casts can be made adapted to be used inprinting-presses.

The machine is designed to form the matrix in wood or any equivalentmaterial in which the characters may be impressed singly or letter byletter; but I prefer to use Wood with its fibers lying in the directionthe impression is made, so that the dies may compress the fibers in theline of their length.

In this machine I employ a rotating typedie wheel in which the type-diesare disposed in radial openings and through which they are forcedagainst the matrix and a swinging matrix-carrier adapted to be locked toand move with the die-wheel during the making of the impression. I alsomake the rotation of the die-Wheel continuous. are forced outward fromthe wheel at the proper time by means of a rotating eccentric locatedwithin the die-wheel and operated intermittently and with the making ofthe several impressions. The shaft carrying this eccentric is providedwith a clutch, one part of which is continuously driven, and which isclosed by the striking of a key-lever to make an impression, thuscausing the eccentric to move through a revolution and actuate thetype-die which at the time is in the proper position to be actuated fromthe eccentric. Means are also provided for releasing this clutch at theproper time and stopping said shaft.

The machine also embodies devices forcoupling the swingingmatrix-carrier to the typedie wheel, devices for releasing suchattachment, and devices for returning the carrier to its normalposition.

All these features of the machine, as well as other details thereof, Ihave fully set forth below, and illustrated in the accompanyingdrawings, in which latter- Figure 1 is a plan, and Fig. 2 a central lon-The dies gitudinal vertical section, of the machine. Figs. 3, 4, 5, and6 are sections upon the lines 3 3, 4 4, 5 5, and 6 6, respectively,'ofFig. 1. Fig. 7 is a section similar to Fig. 6, showing the parts inanother position. Fig. 8 is asection on the line 8 8 of Fig. 1. Figs. 9,10,11, 12, and 13 are details of the matrix-carrier. Fig. 1a shows theface ends of several of the type-dies and their relative arrangement onthe type-wheel.

In said drawings, A represents the cylindrical or die carrying portionof the typewheel. Said wheel consists of said portion A, asupporting-disk a, and a hub 2. It carries one or more fonts of type B,arranged each font in a row running around the cylinder, the type beingdisposed in radial openings with liberty to slide therein. The hub ofthe Wheel is keyed to a hollow and preferably a continuously-rotatedshaft 0 by a key 0, but is movable longitudinally on said shaft by thelever D and the collar d, loosely fitted in an annulargroove of thehub2, to bring the wheel into position to change the font of type beingimpressed. The shaft 0 may be actuated in any suitable 1nanner-as, forinstance, by the spur-gear 3 and the pinion 4:, meshing therewith, thelatter being rigid upon the drivingshaft 5. The type-dies are forcedoutward to impress the matrix by the eccentric E and a plunger actuatedthereby, the former being secured to the end of a journal F, havinga keyor square point fentering a corresponding recess in the end of the shaftG, fitting the interior of hollow shaft 0. Said shaft G is driven fromshaft 5 by the spur-gear 6, pinion 7, loose upon shaft G, and afriction-clutch, which consists of the wheel 8, fast to pinion 7, theband 9, encircling said wheel aud tightened thereon by the spring 10,and the disk 11, fast upon shaft G and connected to and supporting saidband by means of the pin 12. The eccentric actuates in a straight path aslide II, carrying a plunger or point h, which strikes the head or topof the type-dies and forces them to descend upon the matrix. Themovements of the slide are guided by the ways 13 13, carried bythematrix-supporting frame, as hereinafter described, and moving therewith,and the eccentric actuates the slide through the medium of the upper andlower contact-blocks 14 and 15, mounted upon the slide and maintainingconstant contact with the eccentric. The pinion 4 is smaller than thespur-gear (3 on the same shaft 5, and the pinion which drives the shaftG is smaller than the spurgear 3 on the type-wheel shaft 0, whereforethe eccentric E will be revolved much faster than will the type-wheel.The rotation inlparted to the eccentric by shaft G results in theactuation of the slide and plunger while the latter are moving with thetype-wheel and while the proper relative position is maintained betweenthe type and matrix for the making of the desired impression upon thelatter. The slide II is secured to and works upon bracket L, or, morecorrectly speaking, upon the sleeve 2', attached to said bracket andencircling the bearing M, which in turn oncircles said journal F. Thetype are drawn back after the impressions through the medium of the sameeccentric. A cam-groove e in the side of the eccentric actuates at theproper time a lever 28, havinga slidingmove ment upon and supported bythe slide II (or its plunger portion) and with its upper point hookedover and into said groove 6, and causes said lever to move the grippers29, pivotally supported upon the plunger with their upper ends engagingsaid lever into gripping posi tion under the heads 30 of the type. Thecontinued rotation of the eccentric will now lift the type. The grippersare also adapted to be opened by the descent of said lever, and thecam-groove is adapted to give all the necessary movements to the leverand at the proper times to cause these operations by the grippers.

The matrixcarrier consists of a bed-plate J, supported upon swingingbrackets K L, and appropriate devices, to be described farther on, forholding the matrix firmly thereon. The first of these brackets isjournalcd in the hollow shaft 0 and the other upon the journal F. Thismatrix-carrying frame is, as already intimated, intermittently locked toand moves with the type-wheel through a portion of the path of thelatter. The means which I have devised for this purpose I will nowdescribe.

At N is a wheel fast upon the type-wheel shaft 0. Encircling this wheelis a frictionring 0, coupled to the bracket K of the matrix-frame by apin 0, so as to move with the matrix-frame. The ends of ring Oare unitedby a link 02, pivotally joined to one end of the ring and united to theother end thereof bya joint, which permits the tightening of the ringupon the wheel. The tightening action may of course be obtained invarious ways; but a simple method is to employ a movable pivotpin-suchas is shown at 16 and provided with a tapering enlargement-and to makethe openingsin the link and ring to correspond with this pin and permitits movement. Thus the opening 17 in one of the forks of the ring is ofthe diameter of the small part of the pin, while that at 18 in the otherfork is large enough to admit the enlargement of the pin. The opening 19in the link is also of a diameter which will permit the entrance of thetapered part of the pin. In the normal position with the ring loose uponthe wheel the openings 18 and 19 do not exactly register, as shown atFig. 5, and the pin occupies the position also shown at said figure. Nowif the pin be moved so that its enlarged portion is forced to enter theopening in the link this end of the link will be drawn upon sufficientlyto tighten the ring upon the wheel, and thus cause the two to movetogether. I prefer, however, not to rely upon friction alone to move thematrix-frame, and hence I provide upon the link a tooth 20 and upon thewheel a series of recesses 21, each adapted to receive said tooth and toengage therewith when the link is drawn upon to tighten the ring. Thepin is actuated to thus enterwithin and tighten the link and ring witheach stroke imparted to the keys of the machine by the operator, ashereinafter set forth. The matrix-carrying frame thus locked to thetypewheel moves with the latter through a portion of its revolution, theunited movement continuing during the time occupied in making theimpressions. I estimate that the union should continue through aboutone-sixth of a revolution, though this depends, upon the speed and thediameter of the parts, and of course I do not wish to be limited in thisregard. When the limit of the united movement has been reached, the pin16 strikes a stationary cam 22 upon arm 23, and is thereby forced backto its normal position, thereby releasing the strain upon the ring, andthe frame or carrier is now at liberty to swing back to itsstarting-point. It is caused to do this by the following devices: At Pis shown a horizontal shaft in stationary bearings carrying pinions 24and 25, the latter meshing, respectively, with segmental racks 26 uponbracket K and 27 upon bottom of bed J. A spring 1) encircles this shaftP, and as soon as the friction-ringis released from the wheel its powerbecomes effectual to reverse the rotation of the shaft, and thus causethe return of the matrix-carrier.

Inasmuch as the actuating power is applied to the matrix frame orcarrier at its end, it is advisable to prevent any twisting or rackingof the carrier and insure the movement of all parts thereof in strictunison. This Iaccomplishby the employment of the shaft P with twopinions thereon meshing with corresponding racks upon the carrier, onepinion and rack being located at the end of the carrier receiving thepower, and the other pinion and rack being sufliciently near the otherend to counteract the racking or twisting. strain. The flanges upon thepinions also bear upon the sides of the racks and assist in thisfunction. The smooth roller 28, which is employed for another purpose,may also have a flange 29 at one side acting in conjunction wlth theflange or run 30 upon the carrier.

IIO

In the use of this construction the flanges upon the pinions serve tocompel the movement of the carrier in a straight plane, While theintermeshing of the pinions and racks compel both ends of it to swing atthe same instant and with the same speed. I also deem it advisable tosupport the matrix-carrier at the point where the impressions are madeto prevent strains upon the journals, and for this purpose the roller 28may be used, and also a companion roller31. The roller 28 may be on theshaft P, and the roller 31 is preferably given a separate bearing 32 ata point in the rear of roller 28,

The matrix-carrier is provided with suitable devices for holding andfeeding the matrix. When a matrix-block is to be put into the machine,it is inserted in a pocket formed of the laterally-moving.slide R, whichmay be actuated by a thumb-piece r and a loop 33, secured to said slide,the pocket referred to being formed between the slide and the loop, asat 34. At 35 and 36 are guides, between which the matrix moves. NVhenthe matrix-block is inserted the slide R is pulled outward by theoperator a short distance, which enables him to enter the matrix-blockin the pocket with its end against the guide 35. This act positions thematrix-block correctly so far as the distance it should be entered atthe start is concerned. The operator now releases the thumb-piece r, andthe slide It moves backward in obedience to the spring 37 sufficientlyto bring the matrix-block in line with the passage 38 between guides 35and 36.

At S is aspring having a projecting incline s and also provided withhorizontal arms 39, reaching over and bearing upon the top of thematrix-block. At T is another spring, having sharp points 40, designedto enter the matrix-block. These springs are alternate in their actionupon the matrix-block and are rendered so by a rocking-lever 41, pivotedstationarily at 42 and having an outstanding arm 43, connected by apitman-rod 44 to the swinging lever 45, actuated by a cam 46 upon theend of journal F. When the matriX-b1ock is to be held stationary duringthe making of the impression, the spring S is forced to bear upon it bythe point 47 of the rocking lever bearing upon theprojecting eam s, thespring being forced both laterally and downward. This pressure isreleased, so that the holdingspring may retract when the position of thelever 41 is reversed by the movements communicated from the cam 46, theend of the lever bearing the anti-friction roller 43 being now broughtto bear upon the toothed spring T. This latter spring is connected to asliding plate, which is actuated by the type when the impressions aremade, as hereinafter set forth, the slide being moved a distancecorresponding to the width of the letter impressed, and that movement iscommunicated to the matrix-block through the medium of this spring T andits holding-teeth. Said spring T, like the spring S, springs out ofengagement with the matrix whenever the pressure upon it by the rockinglever 41 is withdrawn.

The proper spacing of the impressions is obtained as follows: The typeare arranged in aline running around the periphery of the type-wheel,with the rear or final points of all the letters lying in the samevertical plane, as indicated at Fig. 14. Each type carries near itsoperating or face end a lateral projection Z), corresponding indimension with the width of the letter upon the type plus the width ofthe normal inter-letter space. Thus the letter W is provided with aprojection of considerable width, while the letter 11 carries one ofconsiderably less width. When the dies are forced against the matrix,they enter a funnel orinwardly-tapering guide U, having upon one side aninclined-faced movable section 49, which is struck and moved by theprojectionb upon the type. This movable piece 49 is secured upon the endof a sliding plate 50, moving in ways 51 upon the top of the guides 35and 36, and is confined thereon by the straps 52 53 and screws 54,passing down into posts 55. It will be understood from what has beenwritten that the slide 50 is actuated and the matrix thus moved inadvance of the making of the impression a distance corresponding withthe width of the letter about to be impressed plus the normalinter-letter space. After the making of the impression the slide 50 isretracted by the spring 56, secured at one end to the slide and at theother to the stationary pin 57..

It remains to describe the operating-keys and their connections to thevarious parts of the machine. These keys are shown at RV, and they areall loosely pivoted upon the stationary longitudinal shaft 57. Thatportion of the key-levers extending forward of the pivotal point comesin contact with a movable bar 58 each time a key is struck and liftssaid bar to the position indicated by broken lines at Fig. This bar 58finds support at each end in one of the arms of an elbow-lever 59,journaled upon shaft 57. The other arm of said lever is connected by aspring 00 with a locking catch-bar 61 and rocksthe latter upon itspivotal support 62. The catch 61 is provided with a longitudinal flange63, which when the key is depressed enters the notch 64, formed in theunder side of the key-lever W in obedience to the power of spring 60,which is caused to be exerted by the movement of elbow-lever 59.

The look upon the key-lever just described is released in the followingmanner: Upon the shaft 62 at one end is a notched arm 62, riding uponwhich is a notched lever 62. The arm 62 when the lock has taken placewill occupy a position farther inward than that shown in Fig. 8. Theinner end of lever 62 is joined to a bell-crank lever 62, stationarilypivoted at 62. A spring 62 draws on lever 62 in the direction indicatedat Fig. 8. The lower arm of the elbow-1ever 02 rests when cated at saidfigure.

'jbring said lever'62" inward far enough so that its notch will engagewith the notch of arm The parts remain in this position until i thematrix-frame returns to its position of 1 it comes in contact with theelbow-lever 62: and by rocking said lever forces lever 62 out ward,carrying the arm 62 far enough to throw the catch-bar 61 outofengagement with The engagement between the teeth of lever 62B and arm 62ceases whenf the parts are in their normal position upon the edge of thematrix-carrier, as also indi- It will now be seen that when thematrix-carrier begins to descend and move with the type-wheel theelbow-lever and lever 62 will be free to move in obedience to spring 62This movement will rest, as shown in Fig. '8, in which movement thekey-lever.

they have about reached their normal position of rest by reason of theslope or angle given to the teeth.

Extending from the forward end of the key- 5 levers are pitmen 65, eachjoined to one arm I of an elbow-1ever66,and each of these elbow- Flevers is joined to and actuates a sliding bar upon the stationary shaft68.

broken line in Fig. 3. This contact by the teeth of the spiral with thebar 67 determines which of the type shall be impressed, and

this purpose is served by the locking of the matrix-carrier to thetype-wheel shaft when the latter is in the proper position with the.desired letter over the matrix. In other words, this contactof thespiral with the bar 67 immediately sets in operation mechanism forlocking the matrix-carrier to the type-wheel shaft and also causes theoperation of the clutch whereby the eccentric which forces the i type tomake the impression is set in operation. These features are fullyexplained later The sliding bars rest at their forward ends upon alongitudinal bar 70, which is supported upon two inclined parallelradius-bars 71, pivoted to stationary brackets on the frame. 3 It willthus be seen that when bar 70 is de-' pressed by the contact of thespiral with one of the slides 67 said bar 70 will receive not only adownward movement, but also an endwise one. This latter movement orendthrust enables it to actuate the pivot-pin 16 in setting thefriction-ring 0 down upon the wheel N to lock the matrix-carrier to thetypewheel shaft. Said end-thrust of bar 70 serves the further functionof setting the friction clutch whereby the eccentric for impressing thetype is actuated. This clutch has already been fully described, and itis connectedto said bar 70 so as to be set in operation thereby bar 7 0.

by a link 72, joining bar 70 to a vertical lever 73, pivotedstationarily at 74 so as to swing in the direction of the end-thrust ofThis lever 73 is so positioned that when the parts are in their normalposition it will engage with a lever 75 upon the band 9 and counteractthe tightening power of spring 10, and it is drawn away from thisengagement each time the bar 70 is actuated by the striking of a key. Itis also caused to return to its normal position in season to meet saidlever when the friction-band has completed a revolution by the return ofbar 7 O to its normal position under thepower of the springs '76, actingupon arm 77, rigid upon one of the radius-bars.

The slides 67 all work in slots of a comblike guide 78. Springs 79,joined to the rear end of each of said slides and to their respectiveelbow-levers 66, as shown at Fig. 3, lift the slides to their normalposition as soon as the toothed spiral has depressed the forward end ofthe slides sufficiently to enable it to ,pass clear of the latter.Another-spring is joined to the forward end of the key-levers and to astationary longitudinal bar 81 and acts to retract the key-lever to itsnormal position whenever the lock caused by the catch 61 62 63 ceases.

A sleeve 82 surrounds ,the journal Fand is provided at one end with aflange 83 and at the other end with a screw-thread adapted to receive anut '84. Surrounding this sleeve is the bearing M, provided with ashoulder 86. The sleeve 11 of bracket L of the matrix-carrier isconfined on this bearing between the flange 83 of the sleeve and theshoulder 86 of the bearing,and the journal F is held by shoulder 89 atone end and the nut 87 and thejamnut 88, both threaded on journal F atthe other end.

I have also provided the machine with means which will positively insurethe return of the matrix-carrier to its normal position should thespring 19 fail to perform that function. This mechanism consists of acam 90, mounted upon the outer end of journal F and actuating at onepoint in its revolution the arm 91, carrying an anti-friction roller 92,which receives the impact of the cam. Said arm 91 is rigidlupon a shaft93, journaled in a bearing 93 and carrying another arm or lever 94. Thisarm 94 is joined at 95 to a link 96, which extends to and is pivoted tothe bracket L of the matrix-carrier at 97. The cam is so timedin itsoperation that it will depress arm 91 and lift arm 94: at the propertime to actuate the matrix-carrier and bring it back to its position ofrest. The various parts by which the cam 90 thus actuates thematrix-carrier are all returned to their normal position by the returnof the matrix-carrier itself.

The operation of the machine is substantially as follows: Continuousmotion being imparted to the drive-shaft 5 and carried to the type-wheelshaft by appropriate mechan- ITC ism and a matrix-block being positionedin the carrier, the operator strikes that one of the keys representingthe letter he wishes to impress. This causes a forward movement of theslide 67, attached to the type-key struck, and whenever thecorresponding tooth of the spiral reaches said slide it strikes the sameand depresses it, together with bar 70. This results in the downward andendwise movement of bar and sets in operation the friction-clutch, whichcarries power to the interior shaft G, throughwhich the eccentric E 1sactuated, and at the same time it sets in operation the friction-ringupon wheel N and locks the matrix-carrier to the type-wheel shaft, sothat the carrier begins to move with said shaft. In the course of therevolution of the eccentric and during the time the matrixcarrier islocked to the type-wheel shaft the eccentric forces one of the type intocontact with the matrix. The particular type thus lmpressed being theone corresponding to the key which is struck, the eccentric continues torotate until the friction-clutch by which it 1s driven is released bycontact of lever with lever 73. The matrix-carrier continues to movewith the type-wheel until the pivotpin 16 strikes the cam 22, and isthereby caused to release the friction upon wheel N. As soon as it hasbeen thus released the matrix-frame is returned to its normal positionby the spring 19. 'When the type descends to make the impression, itactuates the slide which feeds the matrix, and said slide, beingretracted after each impression, is of course in position to receive afresh impulse with each actuation of the type. By means ofthe cam 46 thematrix is alternately held and fed, as already described.
